RAILROAD-TIME BULLETIN-BOARD.

SPECIFICATION forming part of Letters Patent No. 267,632, dated November 14, 18E2.

Application filed March 4,1882. (N model.)

To all whom it may concern Be it known that I, JOHN W. WOLCOTT, of

, Clyde, in the county of Sandusky and State of Ohio, have invented a new Improvement in Railroad-Time Bulletin-Boards; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming part of this specification, in which- Figure 1 is a perspective view of my improved bulletin-board taken from the front side; Fig. 2, a perspective view of the same taken from the rear side, and Fig. 3 a perspective view of one ofthe charactenplates and its actu- Wing-arm.

This invention relates to that class of railroad bulletin-boards which are provided with means for changing the announcements made thereby, as occasion requires; and it consists of the peculiar construction and arrangement of the parts, as hereinafter more fully set forth. In the drawings, A represents a bulletinboard, of an y proper form, having proper spaces, a a, for the display of permanent announcements, and proper slots, 0/ a, for the display of special announcements from time to time, as occasion may require.

B represents a frame-planklocated upon the rear side of the bulletin-board and connected securely therewith by means of the braces d, and provided with bearings 12 b and vertical slots 0 e, as shown.

- O represents one of a series ofcurved plates,

having upon its face a row of suitable words or characters, as shown, which isattached to an arm, 0, pivoted to the shaft 0', held by the bearin gs b b.

0 represents a knob upon the rear end of the arm, by means of which it is conveniently actuated when desired.

D represents a curved plate, havinga series of slots, adapted to hold and guide the rear ends of the arms a c, which is provided also with teeth or notches for retaining the arms in any desired position.

The operation will be readily understood. When it is desired to make a special announcement the character-plates are adjusted to bring the proper words, letters, or figures in proper position behind the slot-opening by oscillating the arms 0 on their pivots by means of the knobs c. When properly adjusted. the plates are securely held by the engagement of the arms'c with the notches of the rack-plate D.

"The mechanism described, although exceedingly simple in construction, fulfills perfectly the purpose for which it is designed.

Any desired changes can be quickly and con- 3. The combination of the slotted bulletinboard A, the frame-plank 13, provided with bearings b, slots e,and braces d, and the curved plate D, provided with notched slots,with the oscillating charactenplates 0, provided with the arms a, each having a bearing to receive the shalt c, and a knob, c, at its end, substantially as described, and for the purpose set
